Zed

Zed is a high-performance code editor built from scratch in Rust by the original creators of Atom and Tree-sitter. The core design principle is speed: a custom GPUI GPU-accelerated UI framework renders every frame directly through the GPU rather than relying on a browser engine, resulting in startup times and scroll performance that noticeably outpaces Electron-based editors like VS Code.

Real-time collaborative editing is built directly into the editor, not an extension. Two or more developers can share a Zed project and edit simultaneously with cursor presence, using the Zed server as a relay — similar to Live Share but first-class rather than a plugin. Tree-sitter provides fast, incremental parsing for accurate syntax highlighting and structural selections even in large files.

Zed supports the Language Server Protocol for code intelligence and includes Vim mode, a command palette, and project-wide search via ripgrep. It is open-source (MIT) and runs on macOS and Linux; Windows support is in progress. An optional AI integration connects to Claude and other models for chat and inline edits.
